And of course we can point to societies that culturally “groom” boys to be gay, such as in Samoa where the first boy is raised hetero, and the rest are raised homo. Most of the boys raised to be homo in fact do incline that way, proving the case of nurture over nature when it comes to homosexual inclinations.
On the “born that way” science, I think a queer researcher was caught cooking the books in his “study” during peer review or after the results were examined after publication.
